Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices require frequent software updates, which are time-consuming and expensive when performed at service centers, and existing over-the-air upgrade methods face challenges like memory occupation and potential software installation failures.
Innovation Solution
A communication device and method that utilize multiple radio access technologies to download and upgrade terminal software over-the-air, allowing software to be downloaded via available radio access technologies without occupying resources needed for other communication, and ensuring fail-safe installation by verifying software functionality post-upgrade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated downloading channel is used for software updates, then software update reliability is improved, but device complexity and resource occupation increase
Solution Approach 1:
The patent applies universality by enabling existing radio access technologies to serve dual purposes: normal communication and software download. The system can use any available radio interface (GSM, GPRS, WCDMA, etc.) for both data communication and software update transmission, eliminating the need for dedicated download channels while maintaining reliability through protocol-level safeguards
2Quantity of substance
If old software is overwritten during download to save memory, then memory usage is improved, but communication functionality may be lost
Solution Approach 1:
The patent applies preliminary action by performing verification checks before overwriting old software. The system validates the downloaded software package, checks download completeness, and verifies integrity using checksums or digital signatures before allowing the overwrite operation, ensuring communication functionality is preserved
Solution Approach 2:
The system implements beforehand cushioning by maintaining backup copies of old software versions and implementing rollback mechanisms. If the new software proves defective or causes communication failures, the system can restore the previous working version, providing a safety buffer against potential failures
3Reliability
If service centre update is used, then software update reliability is improved, but time consumption and cost increase
Solution Approach 1:
The patent implements self-service by enabling the mobile device to autonomously perform software updates without requiring service centre intervention. The device automatically detects available updates, downloads them through existing radio interfaces, verifies integrity, and installs updates independently, eliminating travel time and service centre dependency while maintaining reliability through built-in verification mechanisms
4Productivity
If multiple radio access technologies are used for download, then resource occupation for other communication is improved, but download complexity increases
Solution Approach 1:
The patent applies dynamics by implementing adaptive selection of radio access technologies based on real-time network conditions, device capabilities, and current communication requirements. The system dynamically switches between different radio interfaces (GSM, GPRS, WCDMA, etc.) and adjusts download parameters to optimize resource utilization while managing complexity through standardized protocol handling
Data Source
AI summary
The technology downloads and upgrades terminal software of a communications device over-the-air in a efficient and fail-safe manner. The communication device is provided with radio software from a server via a wireless network including a number of access networks. A download is initiated of radio software designed for a first of two different radio access technologies of the communication device. One of the two radio access technologies of the communication device is selected for downloading the software. The radio software is downloaded via the selected available radio access technology. The radio software designed for the first radio access technology is stored in memory.
